It's an ordinary, peaceful market day in Lyngarth when 17-year-old Ren bumps into a troop of soldiers searching for a pair of mysterious fugitives.

After an argument with her father, Ren runs off to the forest where she finds herself in the middle of a dangerous situation.

Hunter follows Ren to her village as the spirit starts to take hold, but before he can persuade her to leave with him her father Dagron returns.

Ren finds herself helpless in the hands of the Kah'Nath while her brother Baynon struggles to find a way to help her by teaming up with an unlikely companion.

When all seems lost Baynon stands up for Ren, spreading doubt amongst the hostile crowd about how 'evil' this new Marked One is, but will it be enough to save her or will Baynon find himself in danger too?

Ren’s new abilities as a Nu’Mahri come shockingly to the fore as she and Hunter flee her village, and Hunter tells her about a mysterious Mahri expert called the Archivist who may be able to help her. Meanwhile the Kah’Nath Master gives Commander Othon an ultimatum.

Ren has a disturbing vision, while Hunter meets with the Archivist’s middleman. The Kah’Nath army leave no stone unturned in their search for the fugitives.

Ren and Hunter strike back against the Kah’Nath, but can Ren control her new abilities? And how far will Commander Othon go to find his quarry?

Ren discovers more about her abilities and her companion as she navigates a strange and dangerous underworld, in the season finale.
